what is this heteroflexibility?
plenty of guys will at least go for blowies if they drunk/high enough.
although i seem to have the frustrating ability to draw admiration and awe from straight friends who WOULD (and/or have) but somehow find me way too intimidating xD
but what is it supposed to mean? if its "almost always hetero but sometimes do homo stuff" well... depend on how often you require the homo stuff to be actually plenty of guys have messed around at least once
imo the barrier is that some guys are just way too hung up on the "if i do this does it mean im gay" internal battle. the ones who don't give a shit are the ones who will occasionally mess around
